RT-PCR ELISA was more sensitive than RT-nested PCR for detection of GBV-C/ HGV RNA. The primers derived from the 5 -NCR was more efficient than those derived from the NS3 and NS5 regions. A reverse relationship was found to exist between HCV RNA concentration and GBV-C/ HGV infection frequency. HGV was the dominant subtype of the virus in the local area. The major mutations of GBV-C/ HGV genomes were random mutation of nucleotide residue.展开更多

An original questionnaire about the current status and awareness of psychological preparation for children in hospitals was distributed by mail to nurses’ working on Japanese pediatric wards in 2010. The same questionnaire, translated into German, was distributed to nurses working on German pediatric wards via the internet in 2010. A large majority of respondents strongly agreed that children have a right to informed consent. German nurses expressed a longer-term viewpoint on the effects of preparation than Japanese nurses. Japanese nurses recognized a greater need for improvement in their duties than German nurses. The results suggest that we should consider our own country’s nursing practices and need for improvement, but also learn from studies of other countries to address each culture and medical situation appropriately.展开更多

Despite existing national and international data on the extent of psychosocial burdens in migrant populations the prevalence among the study population remains unclear. The aim of this study was to collect prevalence data for the largest migrant population in Germany-individuals with Turkish migration backgrounds—using a culturally and linguistically sensitive approach. Methods: The study employs a cross-sectional design. The multi-centre study (Hamburg, Berlin) is based on a sample of individuals with Turkish migration backgrounds living in the two cities stratified by age, gender, and education. The study programme consists of three phases: 1) a qualitative focus group to collect information on how to increase the participation rate of the target population as a minority group in Germany;2) a translation phase to create culture and linguistic sensitive versions of the assessment tools (e.g., the Composite International Diagnostic Interview (CIDI) for Turkish speaking individuals;and 3) a baseline community study to assess the lifetime, 12-month and four-week prevalence and comorbidity rates of mental disorder, health care utilization and help-seeking behaviour in individuals of Turkish migration backgrounds living in Germany. Discussion: The study provides important data on the lifetime prevalence of mental disorders and health care utilization of individuals with Turkish migration backgrounds. Furthermore, the study is an important step towards gaining a better understanding of potential barriers to participation, creating resources for difficult-to- reach minorities, and understanding the need for assessing mental disorders in migrant populations. These results can offer a starting point for the initiation of the necessary structural changes for mental health care services and policies for groups with migration backgrounds.展开更多

Qualified consecutive charts were reviewed in which 5-year efficacy, safety and cost data was abstracted.RESULTS: Seventy-seven latanoprost and 49 timolo patients were included, at the final visit no difference existed between the two groups in disc parameters including: rim area, rim area/disc area ratio, cup volume or vertical cup/disc ratio (P 】0.05). There was no difference in intraocular pressure (IOP) between the initial latanoprost (17.4 ±2.6) and timolol (16.3 ±2.8mmHg) groups. There was less change in medicines over the follow-up period (0.1 vs 0.8) and fewer medications at the final visit (1.2 vs 1.8) with latanoprost compared to timolol. No patient treated with latanoprost discontinued therapy during follow-up, while 12% discontinued timolol mostly due to inadequate IOP control. Cost/year was less with initial timolol ($458±236) as compared to latanoprost ($552±202). CONCLUSION: Patients begun on latanoprost o timolol and followed over 5 years may have similar clinical outcomes. However, timolol patients may require more medicines and medicine changes to control IOP for long-term, but at a lower cost.展开更多

Widespread systems in Germany are closed stables with slatted or partly slatted floor, which produce liquid manure (a mixture of urine, faeces, and cleaning water) whereas in China open stables with closed concrete floors are used with separate collection of faeces and urine. Based on data from literature and own analyses nutrient flows of both systems are calculated. The Chinese manure system or mechanized belt or V-shaped pit floor systems with faeces/urine separation are more effective to separate solids, nutrients, carbon, and heavy metal than mechanical separation from liquid manure. The separation rates can be up to 88% for the solids, 67% for nitrogen, 93% for phosphorus, 60% for potassium, 94% for magnesium, 97% for cupper, and 98% for zinc. The faeces can be used for composting to produce a market product.展开更多

Notwithstanding widespread neglect of its European dimension, this Energiewende will further exacerbate current network fluctuations due to the significant increase in wind and solar power. Key data from Denmark show that this transition will soon bring the German national power system to its limits for absorbing the resulting intermittency, and increase the need for more cross-border power transfers. Yet network analysis of import/export data shows that Germany's position in the European power system is contrary to the Danish case. The need for a European solution for Germany's energy transition will therefore soon become evident. In order to establish the necessary infrastructure, the Energiewende needs hence to be guided by an economic approach designed to prevent further fractures in the Internal Electricity Market. Constructive negotiations with neighbouring countries on market designs and price signals will be important preconditions. The article emphasizes the still neglected European paradox of Germany's energy transition and presents working examples and possible solutions to uphold electricity supply in Europe's power house.展开更多

Consequently, UNICEF and the World Health Organization promote the beginning of breastfeeding within the first hour after birth and recommend to exclusively breastfeed the infant during the first six months. The origins of these modern breastfeeding campaigns can be traced back to the beginning of the twentieth century. Whereas high infant mortality rates traditionally were considered to be a matter of fate and the declining birth rates towards the end of the nineteenth century raised fears about the nation’s future and led to the emergence of an increasing infant welfare movement in imperial Germany. As low breastfeeding rates were identified as a key factor behind the high infant mortality rates, the main objective of the infant care movement was to increase breastfeeding. The paper examines how the context of infant care and infant mortality was constructed and how breastfeeding campaigns in the context of infant mortality, breastfeeding rates and socio-political changes developed during the twentieth century. Thus the paper covers the period from the beginnings of social paediatrics at the beginning of the 20th century, the breastfeeding campaigns embedded into Nazi ideology during the Third Reich, until the declining breastfeeding ratios and the “feeding on demand”-movement in the 1970s as well as the ideological differences between West and East Germany during the Cold War.展开更多

Whereas, before and during the mining process not only nature but sometimes also the population of a whole region has to give way to a mine, the consequences of the operations remain long after mining closure. Typically a once intact and functioning ecosystem is replaced with a destroyed wideness evocative of a moon landscape. Fortunately, the awareness of the need to rehabilitate the destroyed nature is increasing steadily and all involved parties are making efforts to improve the situation, even if it is a major challenge to bring all parties to a consensus. Therefore, a legislative basis is required and the know-how of optimal rehabilitation solutions must be developed. In this article the rehabilitation of mined land in Australia and Germany are compared. More precisely the article will present an overview of the legislative regulations, certain applied methods of rehabilitation work and the problems that are likely to occur in respect to the influence of mining on nature.展开更多

Methods: A total of 80 cases of insomnia with deficiency of heart and spleen in Germany were divided into the observation group and the control group, with 40 cases in each group. The patients in the control group were treated with oral modified Guipi Decoction(归脾汤), while the patients in the observation group were treated with oral traditional Chinese medicine(TCM) and the therapy of ear points pressing with bean. The efficacy, sleep quality, the TCM syndromes score and the incidence of adverse reactions were compared between the two groups. Results: The effective rate in the observation group was higher than that in the control group, and there was statistical difference between the two group(P<0.05). After treatment, the Pittsburgh sleep quality index scale(PSQI) score, insomnia severity index(ISI) score and the TCM syndromes score in the two groups were decreased sharply(P<0.01), and those scores in the observation group were lower than that in the control group(P<0.05). There was no adverse reaction between the two groups. Conclusion: The therapy of ear points pressing with bean is effective on insomnia in Germany, which is worth further study and promotion.展开更多

The scenarios show that the major challenge of a "climate-friendly city transport" can be achieved by appropriate measures (regarding direction and scale): in small and medium-sized cities, large cities, cities of over a million people, and metropolitan regions. The scenarios demonstrate the extent to which the considered measures contribute to the CO2 reduction, and which gap to the achievement of the goal remains if that which is currently regarded as realistic in practice is really implemented in future. Thus, they illustrate the conflict between that which is necessary for climate protection and that which is currently considered feasible in politics. The scenarios show that it is essential to act quickly and appropriately, and not hesitantly or without conviction.展开更多

As a result, its leading role in the EU is apparently on the decline. This change has taken place for the following reasons: internally,it derives from Germany’s domestic political dilemma, changes in its social ecology, and structural defects in its economy;externally, it relates closely to the intensifying interest divides between EU member states, and the major-country global-scale game that is entering a new phase for which Germany is not yet ready. The decline of Germany’s leading role in the EU will intensify rivalry between EU member states, impede the process of European integration, and cause further setbacks to the EU’s global standing. Nonetheless, Germany is aware of this, and is now engaging in profound reflection and active adjustment. Accordingly, the German engine is expected to restart.展开更多

Qualified consecutive charts were reviewed in which 5-year efficacy, safety and cost data was abstracted.RESULTS: Seventy-seven latanoprost and 49 timolo patients were included, at the final visit no difference existed between the two groups in disc parameters including: rim area, rim area/disc area ratio, cup volume or vertical cup/disc ratio (P 】0.05). There was no difference in intraocular pressure (IOP) between the initial latanoprost (17.4 ±2.6) and timolol (16.3 ±2.8mmHg) groups. There was less change in medicines over the follow-up period (0.1 vs 0.8) and fewer medications at the final visit (1.2 vs 1.8) with latanoprost compared to timolol. No patient treated with latanoprost discontinued therapy during follow-up, while 12% discontinued timolol mostly due to inadequate IOP control. Cost/year was less with initial timolol ($458±236) as compared to latanoprost ($552±202). CONCLUSION: Patients begun on latanoprost o timolol and followed over 5 years may have similar clinical outcomes. However, timolol patients may require more medicines and medicine changes to control IOP for long-term, but at a lower cost.

文摘Germany and China use different stable systems for fattening pigs. Widespread systems in Germany are closed stables with slatted or partly slatted floor, which produce liquid manure (a mixture of urine, faeces, and cleaning water) whereas in China open stables with closed concrete floors are used with separate collection of faeces and urine. Based on data from literature and own analyses nutrient flows of both systems are calculated. The Chinese manure system or mechanized belt or V-shaped pit floor systems with faeces/urine separation are more effective to separate solids, nutrients, carbon, and heavy metal than mechanical separation from liquid manure. The separation rates can be up to 88% for the solids, 67% for nitrogen, 93% for phosphorus, 60% for potassium, 94% for magnesium, 97% for cupper, and 98% for zinc. The faeces can be used for composting to produce a market product.

文摘The rehabilitation of coal mines is an up-to-date issue, heavily discussed not only by the industry but also by scientists and the adjacent communities since open cut coal mining has extensive impacts affecting all parties. Whereas, before and during the mining process not only nature but sometimes also the population of a whole region has to give way to a mine, the consequences of the operations remain long after mining closure. Typically a once intact and functioning ecosystem is replaced with a destroyed wideness evocative of a moon landscape. Fortunately, the awareness of the need to rehabilitate the destroyed nature is increasing steadily and all involved parties are making efforts to improve the situation, even if it is a major challenge to bring all parties to a consensus. Therefore, a legislative basis is required and the know-how of optimal rehabilitation solutions must be developed. In this article the rehabilitation of mined land in Australia and Germany are compared. More precisely the article will present an overview of the legislative regulations, certain applied methods of rehabilitation work and the problems that are likely to occur in respect to the influence of mining on nature.

文摘Six German scenario studies on urban passenger transport for Munich 2058, Wuppertal 2050, Eastern Ruhr Region 2030, Tuebingen 2030, Cologne 2020 and Hanover Region 2020 investigate the key question: With which strategies and on what kind of scale, is it possible to reduce the carbon dioxide emissions of urban passenger transport to accomplish the 2℃ climate protection goal with a consequently huge reduction of greenhouse gas emissions by 80% to 95% by 2050 in relation to the base year 1990? The scenarios show that the major challenge of a "climate-friendly city transport" can be achieved by appropriate measures (regarding direction and scale): in small and medium-sized cities, large cities, cities of over a million people, and metropolitan regions. The scenarios demonstrate the extent to which the considered measures contribute to the CO2 reduction, and which gap to the achievement of the goal remains if that which is currently regarded as realistic in practice is really implemented in future. Thus, they illustrate the conflict between that which is necessary for climate protection and that which is currently considered feasible in politics. The scenarios show that it is essential to act quickly and appropriately, and not hesitantly or without conviction.
文摘The paper reports sunthetically the Cocene fauna of the Messel Pit Fossil site of Germany, in detail, including its rich taxanomic composttions, geological and paleogeographic backgroud, and the studying and applying history.
文摘For drinking water security the German waterworks proceed on a comprehensive concept,i.e.,the protection of all the regions from the recharge area to the client.It includes the protection of the recharge area by a precautionary management,a safe water treatment,a strict maintenance of the water distribution network,continuous control and an intensive training of staff.Groundwater protection zones together with effective regulations and control play a very important role.Three protection zones with different restrictions in land-use are distinguished.Water in reservoirs and lakes is also protected by Surface Water Protection Zones.Within the surrounding area the land-use is controlled,too.Special treatment is necessary if acidification happens caused by acid rain,or eutrophication caused by the inflow of sewage.Very important is the collaboration between waterworks and the farmers cultivating land in the recharge area in order to execute water-protecting ecological farming with the aim to reduce the application of fertilizers and plant protection agents.Probable financial losses have to be compensated by the waterworks.
文摘For a long time, Germany played a leading role in the European Union(EU), but in recent years it has reduced its investment in the EU affairs and lessened its enthusiasm for European integration due to its multiple frustrations in maintaining the unity of the EU and leading the EU in global affairs. As a result, its leading role in the EU is apparently on the decline. This change has taken place for the following reasons: internally,it derives from Germany’s domestic political dilemma, changes in its social ecology, and structural defects in its economy;externally, it relates closely to the intensifying interest divides between EU member states, and the major-country global-scale game that is entering a new phase for which Germany is not yet ready. The decline of Germany’s leading role in the EU will intensify rivalry between EU member states, impede the process of European integration, and cause further setbacks to the EU’s global standing. Nonetheless, Germany is aware of this, and is now engaging in profound reflection and active adjustment. Accordingly, the German engine is expected to restart.
